Transcript Kingdom Protista

Living things are . . .
• Organized into
cells.
• Grow and
develop.
• Respond to the
environment.
• Use energy
• Reproduce

6 Kingdoms – Largest
groupings of living things
Plantae

Animalia
Protista
Eubacteria
Archaebacteria
Animal Kingdom
• Multicellular
heterotrophic
• This kingdom includes
all vertebrates (one
major phylum) and
invertebrates (several
phyla)
• Insects, jellyfish,
people are all animals
Kingdom Plantae
Multicellular and
autotrophic
Means that all plants
perform photosynthesis
This kingdom includes
mosses, ferns,
conifers, and flowering
plants (grasses, fruit
trees, shrubs, most
garden plants, most
crops, wildflowers)
Kingdom Fungi
• Multicellular and
some single-cells
• Most of these
organisms are
decomposers
• Includes mushrooms,
yeasts and infections
like athlete's foot
Kingdoms of Single Cells
Kingdom Protista: largest
source of food and
oxygen for the entire
planet. Includes
plankton, amoeba, and
ciliates. Described as
Unicellular Eukaryotes
Prokaryotic Kingdom- Cells without
membraned organelles
• Kingdom Bacteria:
Unicellular
Prokaryotes which
are often
decomposers
• Kingdom
Archeobacteria:
Unicellular
Prokaryotes from
extreme
environments.
Binomial Classification
• Living things are given a two-part scientific
name. This 2-part name is also the species
name. The first part is the Genus which is
capitalized, and the second, which is the
species, part of the scientific name is never
capitalized.
• Scientific names are used because the same
plant or animal in different places may have
different common names.
• Your scientific name is Homo sapiens
Structural System - 1
• Bones are to
– Support &
structure
– Make blood cells
– Allow movement
– Muscle
attachments
– Ligaments hold
joints together
Structural System –
2
• 3 types of muscles
– Smooth, involuntary
– Striated, voluntary
– Cardiac, heart
muscle somewhat
like both above
• Allow for movement
• Attached by tendons
above and below
joints
17 Which structure
in the upper arm is
responsible for
raising the lower
arm?
A1
B2
C3
D4
In order to raise it, it must be attached, so its not 1
or 2.
4 is a bone not a muscle, so its answer:
Nervous System - 1
Consists of brain and
spinal chord
Voluntary, you control
and choose
Involuntary, allows
parts to keep
functioning without
you knowing
Nerve cells send and
receive information .
.
Nervous System Nerve cells have 3
2
parts
– Axon – Sends
signal
– Cell Body –
controls cell
functions
– Dendrite –
Receives signal
from another
– Synapse – space
between cells
Nervous System - 3
• Involuntary is
controlled by the
medulla oblongata of
the brain.
• This is how you keep
breathing while
sleeping and digest
food without thinking
about it.
Circulatory System 1
This
system helps to
connect many other systems
as it provides the transport of
substances from one organ to
another.
Every
cell must touch a
blood vessel to take in what
it needs and get rid of waste.
Arteries
carry blood away
from the heart and veins
carry it back to the heart.
The
heart pumps the blood
Circulatory System - 2
• The top parts of the
heart receive blood –
Atrium
• The bottom two are
very muscular and
pump the blood –
Ventricles
• Two contractions, right
ventricle pumps to the
lungs, and the left
ventricle pumps to the
body and brain.

the brain stem, reacts
quickly to increased
levels of CO2 in the
blood and stimulates a
response from the —
A excretory system
B immune system
C respiratory system
D integumentary system
Increased respiration gets rid of excess CO2
Immune System - 1
• Your immune system protects you
from infections and illness
• 1st Order Non-specific includes
skin, mucous membranes, cilia of
trachea and bronchi, stomach
acid, tears
• 2nd Order includes the
inflammatory response (swelling,
redness due to histamine release),
fever, white blood cells such as
phagocytes and macrophages
destroying the pathogens and
infected tissue cells.
Immune System - 2
•
•
•
Two main types of
immunity
ACTIVE – body makes
its own antibodies after
being sick - permanent
OR a vaccination to
help your body make
antibodies
PASSIVE – injection with
antibodies, or transferred
from mother to unborn
baby
6 Most viruses infect a specific kind of
cell. Which of the following are infected
by the human immunodeficiency virus
(HIV)?
F Helper T cells
G Liver cells
H GABA-receptor cells
J Red blood cells
Plant Systems
• There are 3 main plant
systems:
• Reproductive – this is the
flower structure
• Transport – this is the
stem and roots and their
xylem and phloem
• Energy – this is the leaf
and other areas of
photosynthesis.
